My mom recently married her long term boyfriend John. What she doesn't know is for the past two years we've been having the most intense, erotic and unashamedly sordid affair. It started after they'd had a huge argument, John left to stay with a friend, and my mom decided to have sex with a neighbor after John had been gone for two days. I walked back into the house to find her fucking the guy (Or more to the point, the guy was hammering away at my moms asshole). John found out and they split for a while. It was during their split I met him at a bar to try and mediate between them. It didn't work out that way, as I ended up going to a motel with John.
The sex was just amazing and I couldn't figure out why my mom would want to ditch this horny well endowed man. In the two hours we spent having sex, John made me cum at least a dozen times. And believe me we did absolutely everything together. His cock which I now know to be just over nine inches in length, remained rock hard throughout as he'd popped a pill. It gave me the oportunity to see what it was like to have a real hard big cock fucking my asshole for the very first time. I simply couldn't get enough of his cock deep inside my bowels and in a series of orgasms I practically screamed the place out. When we left the motel owner gave me a knowing look and squeezed Johns shoulder, as if to say, "well done buddy you certainly gave it to her".
We've been fucking whenever we can ever since. I know I shouldn't be having sex with my now step father, but I just help myself, and I now long for John to fuck me as hard as he can. Visiting mom over the past two years has been frustrating at times, but when she's out cold from her wine drinking, myself and John indulge in some very dirty horny and always orgasmic sex.
